MY CODE : import java.util.*;
public class prime
{
public static boolean prime(long a)
{
int c=0;
for(int i=1;i<=a;i++)
{
if(a%i==0)
c++;
}
if(c==2)
return true;
else
return false;
}
public static void main()
{
Scanner sc=new Scanner(System.in);
long n,u,l;
n=sc.nextInt();
if(n>1000000000)
System.exit(0);
for(long l1=1;l1<=n;l1++)
{
l=sc.nextInt();
u=sc.nextInt();
if(u-l>100000)
System.exit(0);
for(long i=l;i<=u;i++)
if(prime(i))
System.out.println(i);
}
}

hey, solution link for your code, its now giving NZEC 
But yeah i removed the compiler error, it was because you file was getting saved on server as palin.java, and your class name was also palin, just changed the class name.
now work on this NZEC

Your class name is not " Main ".
For Java in codechef online judge have two options
- public class Main{
public static void main (String[] args) throws java.lang.Exception {
// your code here
} }
- class YourClassName{
public static void main (String[] args) throws java.lang.Exception {
// your code here
} }
Remember " the name of the class has to be “Main” only if the class is public. "
If you use some other class do not declare it public, see my example here.
For more information check codechef sample for java here.
Hope this helps.
